Problem above, I use the distance formula from the focus to the intervals(0/20/40/60/80/100).
I use x2=4(1/4)y as the formula but end up with answers far too large using the distance formula.
Where am I going wrong?
finding a formula on my calculator(guessing and checking parabolas that fit into the given coords)
gives me the solutions, is there no other way to solve without a calculator?Feels like I'm cheating
formula is y=.004x^2
